OF THE GENUS PINUS. 607 
allied species a description of the true halepensis is here given. 
The branches are usually ashen-gray, cracked vertically, and 
marked with oblong obtuse projecting phyllules. The smaller 
branches are slender, pliant, subangular, destitute of leaves 
except near the extremities. The free portion of the pulvinus, 
or phyllule, is often more or less orange-coloured, the persistent 
part adnate, oblong, with a rounded end, a prominent midrib, 
and a deep furrow on either side separating it from the adjacent 
leaf-scar. The upper part of the primary leaves is membranous, 
revolute, and deciduous. The lower part of the scales con- 
stituting the leaf-sheath are persistent, convolute, coriaceous, 
the upper portions membranous and deciduous, leaving, after 
their fall, a truncated edge. The leaf-buds are small, slender, 
cylindric-conic, their scales deltoid acuminate, chestnut-brown, 
lacerate at the edges. The leaves are slender, arranged in pairs, 
and of varying length in different specimens. ‘The boat-shaped 
leaf-section shows a very thick hypoderm with marginal resin- 
canals surrounded by a sheath of stereome. The meristele is 
transversely oblong, and the fibro-vascular bundle branched, with 
a mass of thin-walled cells between the subdivisions. The 
endoderm-cells are about 36 in number. The male flowers are 
congested in globose or racemose heads, each flower 7-8 mill. 
long, oblong-obtuse, orange-coloured or pale yellow; connective 
suborbicular, crenulate. Cones iu pairs or solitary, on thick, 
deflexed stalks, each cone about 7-8 cent. long, oblong-conic, 
chestnut-brown or greyish; apopbysis either prominent or flattish, 
with radiating lines and a prominent rhomboid transversely 
keeled umbo. Cotyledons 6-9. 
The preceding notes ave, with the exception of that relating to 
the cotyledons, taken from a wild specimen forwarded to me 
by the late M. Naudin from Antibes, with the intimation that it 
grew on “terrains caleaires et rocailleux des environs de la 
Méditerranée.” From the same source other specimens labelled 
P. maritima, Lambert, from the ‘“ sables maritimes pres 
d’Antibes,” were received. These differ from the halepensis 
above described in their longer, less slender foliage, and in their 
male flowers being in long dense spikes or racemes. Un- 
fortunately no cones were sent with this latter form. 
Tenore, Flora Napol. v. p- 267, describes two varieties —one 
with oblong cones and flattish scales, the other with ovate-couic, 
blackish cones and prominent apophysis. To this latter he refers
